Release note (backward-incompatible change): There was a bug whereby, when server.identity_map.configuration was used, CockroachDB did not verify the client-provided username against the target mappings. This bug was fixed; however, this also means that the client must now provide a valid DB username. This requirement is compatible with PostgreSQL; it was not previously required by CockroachDB but it is now.

(This note does not apply when identity maps are not in use.)
